Abstract:
Disclosed is a collision energy absorbing structure of a vehicle capable of relieving impact by using a tubular pipe member having equally-sized rectangular cross section and equal plate thickness and including no inside ribs and by adding a suitable trigger, and being easily manufactured at a low cost. By forming a cutout portion on the left side of the front end portion of the collision energy absorbing structure, the deformation starting portion is provided. The cutout portion is formed at parts of three flat plate portions comprised of one of the four flat plate portions and corresponding opposite portions thereof. The general portion, which follows the deformation starting portion, is tubular with rectangular cross section and has a closed cross-section structure.

Abstract:
There is provided a railcar including a under frame, paired side bodyshell parts, and a roof bodyshell part. Strap bar receiving parts hanging downward from the roof bodyshell part are fixed to the roof bodyshell part. An upper horizontal member and a lower horizontal member are provided like bridges between the paired side bodyshell parts. The upper horizontal member and the lower horizontal member are disposed at an interval in a vertical direction and connected by connection pipes. The upper horizontal member is formed by a plurality of reinforcement pipes and the lower horizontal member is formed by a plurality of reinforcement pipes. At least one ends of the plurality of reinforcement pipes are fixed to the strap bar receiving parts.
Abstract:
A laminate-packaged electric storage device includes an outer package, an electric storage device element, and an electrolyte solution, the outer package formed by stacking and seal-tight bonding outer package films along a bonding section formed in an outer edge area of the outer package films, the electric storage device element and the electrolyte solution being held in a receiving section formed inside the outer package. A non-bonding section surrounded by the bonding section and communicating with the receiving section is formed in the outer edge area, an opening is formed through at least one outer package film, and a seal section is formed to surround the opening formed in an area of the non-bonding section, the outer package films bonded in the seal section, and the opening formed in the area of the non-bonding section at a position other than a center position.

Abstract:
A bodyshell of a railcar includes side outside plates, end bodyshells, and guiding plates. The side outside plate are located at both end portions of a carbody in a vehicle width direction. The end bodyshell includes an end outside plate and a corner post. The end outside plates are located at both end portions of the carbody in the longitudinal direction. The corner posts are located at four corners of the carbody. The corner post is joined to the adjacent end outside plate and the adjacent side outside plate. The guiding plate is provided at the side outside plate so as to cover the corner post from a vehicle exterior. The guiding plate includes an inclined portion and a joining portion. The inclined portion is provided in front of the corner post and inclined to the rear side toward the side outside plate.
Abstract:
A wound-type accumulator is equipped with a cylindrical wound electrode unit, which has belt-like positive electrode and negative electrode and configured by winding an electrode stack obtained by stacking the positive electrode and negative electrode through a separator from one end thereof, and an electrolytic solution. The negative electrode and/or the positive electrode is doped with lithium ions by electrochemical contact of the negative electrode and/or the positive electrode with a lithium ion source, intra-positive electrode spaces are formed in the positive electrode, and at least one lithium ion source is provided in the intra-positive electrode space or at a position opposing to the intra-positive electrode space in the negative electrode in a state coming into no contact with the positive electrode.
